Danke mit dem tip das ich an der Makefile basteln muss, ich habe CROSS_COMPILE und ARCH entsprechend gesetzt, und bin jetzt stolzer Besitzer eines 64-bit Kernels! :-)) Ich versuche nun eine statisch gelinkte toolchain in /tools aufzubauen, um damit ein volles 64-bit System zu basteln (siehe LFS 5.0). Aber leider weigert sich gcc-3.2.3 sich selbst zu kompilieren. Ich versuche also mit meinem 32-bit gcc-3.2.3 cross-compiler fuer x86_64 (ist im PATH drin) nun einen 64-bit gcc zu stricken. Ich bekomme aber leider nur die am Ende der Mail angehangene Meldung. Hat da irgend jemand villeicht Erfahrung oder auch nur eine Idee woran das liegen koennte ???
